@PECIPICATION forming part Of Letters Patent No. 378,539, dated February28, 1888.

Application filed July 17, 1886. Serial No. 208,322. (No model.) i

To all whom, it may concern:

Be it known that we, J AMES E. Borsronn, a citizen of the United Statesof America, residing in the city of Auburn, Cayuga county, and State ofNew York, and, THoMils L. CHURCH, also a citizen of the United States,residing in the city of Syracuse, county of Onondaga, and State of NewYork, have i11- vented a new and useful Improvement in a Draft-Shackle,of which the following is a specification.

The object of the invention is to have a draftshackle for vehicles thatwill always be tight and close around the bolt connecting it with theclip on the axletree, preventing any noise or rattling, and also to havea shackle by which shafts or poles can be removed or attached quickly.\Vc attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of theshackle closed, and Fig. 2 represents the same open.

In the drawings, the letters A A represent the eye of the shackle. Fig.1 represents the shackle with the eye A A closed around the bolt E ofclip attached to the axle-tree of 2 represents the shackle with the eyeopen and spring thrown up so as to remove the thills.

B B represent the two parts of the shackle, the one part hinged to theother at point H.

0 represents an adjustable yoke around the two parts of the shackle.

D-represents the spring which presses the yoke 0 onto the shackle B Band keeps it closed tightly around the bolt E.

E represents the bolt to which the clip is attached.

F represents a tight collar around the bolt and rests against the pin G.The collar F and the pin G prevent the spring D from sliding along theshackle-bar J.

H represents the hinge of the shackle, and by means of which the shacklemay be opened and shut when the spring D is pushed down to the collar F.

The two parts B B are made on an incline, so that when the shackle isattached to the carriage the adjustable yoke O is pressed along theincline by spring D, closing the eye A A and holding it firmly aroundthe bolt E, thus making any rattling of these parts an impossibility.The slight opening in eye A A, as shown in Fig. l, is to provide for anywear of bolt E, permitting the eye to close as the bolt may wear, thepressure from the adjustable yoke O and spring D keeping the eye A Afirmly in place around bolt E.

To attach or detach thills or pole with this shackle only requires aslight pressure from the thumb and fingers, pressing back yoke O andspring D to the collar F, and thus permitting the eye A A of shackle toopen, as in Fig. 2.

In the drawings the letters represent the various parts of adraftshaekle as follows: A A, the eye; E, the bolt of clip on axle-treeof carriage, said bolt resting in the eye of shackle when thills or poleare attached to carriage; B B, the two parts orjaws ofthe shackle, theone part hinged to the other; (i, the adjustable yoke; D, the spring; H,the hinge, hinged with or without a rivet; F, the collar; G, the pin; J,the bar of the shackle.

WVe claim as our new invention Adraft-shackle comprising two hingedjaws, B B, a divided eye, A A, a yoke, O, and spring D, all combined andoperating as above described, together forming an improved selfadjustingdraft-shackle for vehicles.
